* Clean up mostly unused IOSPACE macrosDavid Gibson2007-05-08
| | | | | | | | | | | | | | | Most architectures defined three macros, MK_IOSPACE_PFN(), GET_IOSPACE() and GET_PFN() in pgtable.h. However, the only callers of any of these macros are in Sparc specific code, either in arch/sparc, arch/sparc64 or drivers/sbus. This patch removes the redundant macros from all architectures except sparc and sparc64.

* [ARM] 4158/1: Fix user page protection macrosImre_Deak2007-02-11
| | | | | | | | | | The PAGE_* user page protection macros don't take into account the configured memory policy and other architecture specific bits like the global/ASID and shared mapping bits. Instead of constants let these depend on a variable fixed up at init just like PAGE_KERNEL.

* [ARM] Unuse another Linux PTE bitRussell King2006-12-13
| | | | | | | | | | L_PTE_ASID is not really required to be stored in every PTE, since we can identify it via the address passed to set_pte_at(). So, create set_pte_ext() which takes the address of the PTE to set, the Linux PTE value, and the additional CPU PTE bits which aren't encoded in the Linux PTE value.

| * [ARM] 3859/1: Fix devicemaps_init() XIP_KERNEL odd 1MiB XIP_PHYS_ADDR ↵George G. Davis2006-09-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | translation error The ARM XIP_KERNEL map created in devicemaps_init() is wrong. The map.pfn is rounded down to an even 1MiB section boundary which results in va/pa translations errors when XIP_PHYS_ADDR starts on an odd 1MiB boundary and this causes the kernel to hang. This patch fixes ARM XIP_KERNEL translation errors for the odd 1MiB XIP_PHYS_ADDR boundary case. Signed-off-by: George G.

* | [PATCH] Standardize pxx_page macrosDave McCracken2006-09-26
|/ | | | | | | | | | | | | | | | | | | | | One of the changes necessary for shared page tables is to standardize the pxx_page macros. pte_page and pmd_page have always returned the struct page associated with their entry, while pte_page_kernel and pmd_page_kernel have returned the kernel virtual address. pud_page and pgd_page, on the other hand, return the kernel virtual address. Shared page tables needs pud_page and pgd_page to return the actual page structures. There are very few actual users of these functions, so it is simple to standardize their usage. Since this is basic cleanup, I am submitting these changes as a standalone patch. Per Hugh Dickins' comments about it, I am also changing the pxx_page_kernel macros to pxx_page_vaddr to clarify their meaning.

* [ARM] nommu: adjust headers for !MMU ARM systemsRussell King2006-06-28
| | | | | | | | | | | | | | | | | | | | | Majorily based on Hyok Choi's patches, this fixes up the asm-arm header files for mmuless systems. Over and above Hyok's patches: - nommu.h merged into mmu.h (it's only a structure) - nommu_context.h is essentially the same as mmu_context.h, but without the MM switching code. so there's no point having separate files. Also, in memory.h, there's no point #ifndef'ing PHYS_OFFSET and END_MEM - both CONFIG_DRAM_BASE and CONFIG_DRAM_SIZE will always be set by the configuration scripts. Other files have minor formatting changes, but are essentially the same. Hyok's original patches were signed off thusly: Signed-off-by: Hyok S.

* [ARM] 3439/2: xsc3: add I/O coherency supportLennert Buytenhek2006-04-01
| | | | | | | | | | | | | | | | | | | | | Patch from Lennert Buytenhek This patch adds support for the I/O coherent cache available on the xsc3. The approach is to provide a simple API to determine whether the chipset supports coherency by calling arch_is_coherent() and then setting the appropriate system memory PTE and PMD bits. In addition, we call this API on dma_alloc_coherent() and dma_map_single() calls. A generic version exists that will compile out all the coherency-related code that is not needed on the majority of ARM systems. Note that we do not check for coherency in the dma_alloc_writecombine() function as that still requires a special PTE setting. We also don't touch dma_mmap_coherent() as that is a special ARM-only API that is by definition only used on non-coherent system.

* [ARM] Control v6 'global' bit via Linux PTE entriesRussell King2005-08-10
| | | | | | | | | | | | Unfortunately, we can't use the "user" bit in the page tables to control whether a page table entry is "global" or "asid" specific, since the vector page is mapped as "user" accessible but is not process specific. Therefore, give direct control of the ARMv6 "nG" (not global) bit to the mm layers. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
